ABSTRACT:
A photoconductor element is provided that has non-blurring latent image keeping memory which is suitable for multiple electrophotographic copying from a single imaging step. The element preferably incorporates a charge generation layer which comprises a phthalocyanine dye or pigment. The copying method involves simultaneous application of corona charge and an image exposure to the element followed by uniform irradiation of the element. Thereafter a plurality of copies can be made by the step sequence of toner deposition, toner transfer, and toner heat fusion to a receiver.
